The question simply ask to write the partial fraction decomposition of the rational expression.
(x^2) / (x^4 - 2x^2 - 8)
I wrote it out as:
(A / (x-2)) + (B / (x+2)) + ((Cx+D) / (x^2+2))
I got as far as simplifying it as:
So I group them up as:
Now I'm lost in using the elimination method because I just don't see how to peace together this puzzle, and the use the answer to complete the partial fraction decomposition. OMG I need some assistance please, this problem is driving me mad...
